This is definitely an intriguing issue and is worth investigating with
subjects from different parts of the world. An informal discussion in my
Human Factors Engineering class resulted in mixed preferences. The
reasons for not accepting the rule universally could be as follows:

a. It depends on the application.
b. It depends on whether the controls are to be operated by both hands
   or one hand.
c. There is a definite difference in preference between left-handed and
   right-handed persons.

Note: Would like to hear comments from fellow netters.
